On the day after her release, Keiko Aoki, 51, along with her de facto husband, Tatsuhiro Boku, 49, visited the grave of her daughter, who was killed at age 11 in a fire in 1995 for which the two were convicted and sentenced to life in prison.

The Osaka High Court on Monday ordered their release following a decision to reopen the arson-murder case.

Aoki said that she has prayed for her daughter Megumi every month on the day of her death. She had said publicly that she wanted to offer prayers at her daughter's grave in Nara Prefecture as soon as possible, preferably immediately following her release.
